| Given the principles of organic agriculture, nutrient cycling in Dutch organic farming can be characterised as imperfect, mainly because of large imports of nutrients from conventional agriculture and from abroad. Recently, research has been initiated into the perspectives for better closing nutrient cycles by intensifying the exchange of (by-)products between organic farming sectors. The linear programming model was developed to quantify under different scenarios the agronomic consequences of further closing nutrient cycles in terms of changes in land use and exchange of (by-)products. Better closing of nutrient cycles requires an increase in the proportion of Dutch feed ingredients in animal diets, an increase in the proportion of feed and leguminous... |
